oracle retail demand forecasting

January 7, 2021

Retailers can now improve inventory management through a single view of demand throughout their entire product lifecycle with the next generation Oracle Retail Demand Forecasting (RDF) Cloud Service. While this is of key concern for various optimization solutions of the forecast, the technical details are beyond the scope of this document. This method lets the Multiplicative Seasonal and Additive Seasonal models compete and picks the one with the better fit. Initially the implementation of RDF was going to cover FMCG, hardlines, textiles and electronics and complete within one year. An individual promotion represents the case where for a particular time period a single promotion is enabled. A style/store forecast is generated, and the forecast data is spread back down to the item/store level. The most common statistical methodologies used are univariate. The system determines the multiplicative and additive weights that best fit the data on hand. As forecasting consultants and software providers, Oracle Retail assists clients in obtaining good forecasts for future demands for their products based upon historical sales data and available causal information. The current RDF Seasonal Regression forecasting model is designed to address these needs. Content will be entered on the day of the Critical Patch Update release. Solution allows retailers to maintain a single projection of forecasted demand across all commerce anywhere operations efficiently and accurately. Because sales histories of longer than two years are often difficult to obtain, many retail environments need a seasonal forecast that can accommodate sales data histories of between one and two years. Causal Forecasting uses stepwise regression to determine which causal variables are significant. In this case, three parameters are used to control smoothing of the components of level, trend, and seasonality. Developing compelling and unique assortments through optimized retail planning continues to be the key for retailers to compete in this increasingly complex industry. The Automatic Forecast Level Selection feature of the system automates the selection of best aggregation level (forecast source-level) for each product/location combination. A simple moving average forecast involves taking the average of the past n time periods and using that average as the forecast for all future time periods (where n is the length of fitting period). a function of level, trend, seasonality and trend dampening factor. If yes, move on to Step 7. ORACLE RETAIL DEMAND FORECASTING. READ OUR RETAIL FORECASTING BLOG REQUEST A DEMO Engage with … It is the simplest model of the exponential smoothing family, yet still adequate for many types of RDF demand data. As point-of-sale data becomes available, the forecast is adjusted and the scale becomes a weighted average between the initial plan's scale and the scale reflected by known sales history. In answering that question (in a particular scenario), suppose that we have determined that 13 weeks of history is the transition point. It is especially effective for new products with little or no historic sales data. Oracle Retail’s Demand Forecasting Cloud Service (RDF CS) empowers retailers to centralize demand forecasts — from operations and vendor collaboration to … Link to Product Website: https://www.oracle.com. Copyright © 2018, Oracle and/or its affiliates. Bayesian forecasting is primarily designed for product/location positions for which a plan exists. Aggregate the preprocessed continuous day level promotional variables to the week level. Overlapping promotions represents the case where there are two or more promotions that happen at the same time period at the same location for the same product. Each forecast observation reflects a future value of the sole input variable. Set promotional effects if desired. A combination of several seasonal methods. The following are major problems in automatically developing these forecasts: The lack of substantial sales history for a product (which especially makes obtaining seasonal forecasts very difficult). Through training, you will learn about traditional forecasting through a variety of forecast methods and how to leverage this solution to help your business align operations across global networks. Manage, control, and perform seamless execution of day-to-day merchandising activities, including purchasing, distribution, order fulfillment, and financial close. If no, move on to Step 9. The Seasonal Regression Model is included in the AutoES family of forecasting models and is thus a candidate model that is selected if it best fits the data. Does the time series contain any data point with sales equal qualify to forecast using Additive Winters method? User input in overriding the automatic training horizon further enhances the simple robustness of this model for base-level data.

This improves forecasts created using Holt over longer forecast horizons. If there have been significant shifts in the level of sales from one year to the next, the model learns that shift and appropriately weigh last year's data (keeping the same shape from last year, but adjusting its scale). Our client is one of the largest hypermarket chains in the world and had been using an outsourced service to calculate sales forecast. Because of this difference, Bayesian Forecasting is not included in AutoES. 3) User Guide RPAS Fusion Client(Rev. The scheduling of the Automatic Forecast Level Selection process (AutoSource) must be integrated with the schedules of other machine processes. This method does not generate confidence and cumulative intervals. Time series methods extrapolate features from the past (in this case, past sales data) to the future. 27th February 2018 . Refer to Multiplicative Winters Exponential Smoothing in this document for a description of each of the forecasting approaches. Char&Yatfield, International Journal of Forecasting, March 1992. Retail Cloud Notice potential customers and their needs, which can be incorporated into your services. Thus, the output from the algorithm is a selection of promotional variables and the effects of those variables on the series. Forecast accuracy depends on the degree to which a mathematical model can detect and extract statistical patterns from historic data. Oracle Inventory Optimization Enables Retailers to Navigate Uncharted Demand ... Service can sit between a retailer's forecasting and supply chain systems to help highlight ... Oracle Retail. Oracle Retail Demand Forecasting enables you to manage a single forecast to drive profitable planning and operations reflecting customer preferences. Then the forecast is generated and proportionally spread down to the final-level. Leverage forecasted demand across all commerce channels to guide a time-phased inventory ordering, allocation, replenishment, and delivery plan to all levels of the distribution network. Oracle Learning Subscriptions | Learn Oracle from Oracle. home nav. When this forecasting method is selected, the forecasts are seen as trending either up or down, as shown in Figure 3-5. Implementing Oracle Retail Demand Forecasting. In addition, the Additive and Multiplicative Winters models search for short-term trends and have difficulties with trends occurring inside the seasonal indices themselves. The spreading utilizes causal daily profiles, thus obtaining a causal forecast at the day granularity. In this case, the Croston's model is applied.

The absence of a check mark in this measure causes the system to default to the Default Source level or the Source Level Override value if this has been set by you. The alpha is capped by 0.5 by default or the Max Alpha (Profile) value entered by the user. Oracle Retail Demand Forecasting is highly flexible, and can be configured to take into account your unique demand drivers, like pricing or promotions. Advanced Inventory Planning - Oracle Retail Oracle Retail Demand Forecasting Related Parameters 7 .3 documentation My Oracle Support Documents Oracle Retail Demand Forecast EP interface design and documentation 2. In some instances, no promotional variables are found to be statistically significant. The same can be said for any two events that always occur at the same time. The best aggregation status keeps track of which sub-problems have been performed and which sub-problems remain. Promotional variables, internal promotional variables, promotional variable types, and the series itself are passed to the stepwise regression routine, with the historic data serving as the dependent variables. Analytics and Machine Learning in Retail: Demand Forecasting and Price Optimization . Given that both sales plans and time series forecasts are available, an obvious question exists: When should the transition from sales plan to time series forecasting occur? In such instances, expert knowledge (generally in the form of sales plans) is required. The optimal smoothing parameters for each model form are determined automatically (that is, greater smoothing is applied to noisier data). The regression method provides a much better forecast of the series than was possible with the other exponential smoothing algorithms. The following topics present fundamentals of the RDF statistical forecasting processes. The binary creates an internal promotional variable to allow the modeling of trend. Oracle Retail Demand Forecasting (RDF) is a statistical and promotional forecasting solution. The data used to fit the regression is the fit history of each time series, so basically a model is fit per time series. Daily profiles are calculated using the Curve module. The Holt model provides forecast point estimates by combining an estimated trend (for the forecast horizon - h) and the smoothed level at the end of the series. In actual practice these algorithms have been and can be used to forecast a myriad of different data streams at any product/location level (shipment data at item/warehouse, financial data at dept./chain, and so on). The de-causalized daily profiles capture the day-of-week effect and should be quite stable. If no, move on to Step 9. This forecasting guidebook covers two case studies executed with MIT and Oracle Retail on how adaptive intelligent applications leverage machine learning and AI to deliver significant results for retailers. Overview Dashboard: Contextualize forecasting impacts to key performance indicators. The problem arises when attempting to forecast products with little or no history. This method captures the trend of a series through the slope of the regression line while the series shifted by a cycle provides its seasonal profile. The final selection between the resulting models is made according to a performance criterion that involves a trade-off between the model's fit over the historic data and its complexity. Identifying the best aggregation levels for sets of products and locations can be divided into a number of sub-problems: Determining the best source-level forecast. RDF is able to use several time series methods to produce forecasts. The Retail Demand Forecasting Cloud Service provides accurate forecasts that enable retailers to coordinate demand-driven outcomes that deliver connected customer interactions. Details; Back; Use machine learning techniques to estimate historical lost sales and predict future demand of new items. This method only generates confidence and cumulative intervals when a source level is specified and the source and final levels are the same. A description of the competing models used within AutoES is described in "Exponential Smoothing (ES) Forecasting Methods". All rights reserved. Oracle Retail Demand Forecasting Cloud Service Empower Demand-Driven Retailing Maximize forecast accuracy for the entire product lifecycle with next-generation retail science paired with exception-driven processes and delivered on our platform for modern retailing. Otherwise, the system assumes a plan exists and equals zero and acts accordingly. The Oracle Retail experience in promotional forecasting has led us to believe that there are a few requirements that are necessary to successfully forecast retail promotions: Baseline forecasts need to consider seasonality; otherwise normal seasonal demand is attributed to promotional effects. Check the spelling of your keyword search. If there is too little data to create a seasonal forecast (in general, less than 52 weeks), the system selects from the Simple ES, Trend ES, and Intermittent ES methods. As forecasting consultants and software providers, Oracle Retail assists clients in obtaining good forecasts for future demands for their products based upon historical sales data and available causal information. Predictions from these various models gives the estimated mean outcome. Does the time series contain the minimum data points to qualify to forecast using the Croston's method? Figure 3-6 Multiplicative Winters Exponential Smoothing. If yes, generate a forecast and statistics using the Holt method and move on to Step 5. The profiles are multiplied by the causal effects and then the profiles have to renormalize. When the Multiplicative Seasonal forecasting method is selected, the forecasts tend to look squiggly, as shown in Figure 3-6. Any time period with non-zero Actuals for a given product/location position should have a corresponding plan component. Retail Cloud Set achievable targets for commercial growth, sales, and latest product developments Recently, Oracle Retail evaluated the next-generation, cloud-native, retail demand forecasting solution against Best Buy’s current on-premises version where end-users were manually adjusting 50 percent of forecasts and found a 70% improvement of promotional forecasts. The following procedure outlines the processing routine steps that the system runs through to evaluate each time series set to forecast using the AutoES method. If no, do not forecast and go to the next time series. Within RDF, a few modifications to the standard selection criteria have been made. As illustrated in Figure 3-2, a final forecast is generated by: Aggregating up from the base level to the source-level, Spreading the source-level forecast down to the final-level. These changes tend to favor the seasonal models to a slightly higher degree that improves the forecasts on retail data, especially for longer forecast horizons. Frequently, clients already have some expectations of future demands in the form of sales plans. Providing multiple forecasting methods is only valuable if the appropriate model can be selected in an accurate and efficient manner. In this process, historical data is used to generate a forecast for a test period for which actual sales data already exists. Description. If this is the case, the method rejects itself out of hand and allows one of the other competing methods to provide the forecast. The causal forecasting process has been simplified by first estimating the effects of promotions. Now assume that the same promotion is held in a future week (w36), but only on Thursday: Then the continuous weekly indicator for w36 should be set to 0.1, which is the weight of Thursday only. Forecasts for short horizons can be estimated with Simple Exponential Smoothing when less than a year of historic demand data is available and acts-like associations are not assigned in RDF. 3038984 Mar 11, 2016 4:19 PM In the forecasting process when RDF sees a regular price change, we know that it applies an elasticity value, decay factor and effective periods. The models in the candidate list include: These models include level information, level and trend information, and level, trend and seasonality information, respectively. The effects can be either: Calculated. The Profile-based forecasting method can be successfully used to forecast new items. They are smoothing models because they use weighted averages on historic data. The technical methods used are driven by the goal to provide the most accurate forecasts possible in an automatic and efficient manner. This forecast represents the final forecast. The selection of the best level is based on a train-test approach. Leverage a highly visual, intuitive, end-to-end workflow to define and execute local market assortments, improve conversion of traffic into sales, and increase customer satisfaction. This method is generally used for known seasonal items or forecasting for long horizons. With Oracle Retail Demand Forecasting RETAIL MARKET REALITIES THE UPSIDE OF UPGRADING MODERN RETAIL IMPERATIVES FUTURE PROOF INVESTMENT With over 5,280 customers worldwide, Oracle is the platform for modern retail around the globe. Simple moving average forecasts are frequently used in the system because they: Make few assumptions about the historical time series. Copy Forecasting Method copies the measure that was specified as Forecast Data Source in the Forecast Administration Workbook into the Forecast measure. The binary writes the winning promotional variables effects back to the database. The second noise-driven concession is to check the slope to determine if it is either too slight or too great. A final-level forecast is generated for each product/location combination using each potential source generation level. In this case, base-level sales data is aggregated from the item/store level up to the style/store level. The Seasonal Regression Model uses simple linear regression with last year's data as the predictor variable and this year's sales as the target variable. When calculating the causal forecast, the calculated causal effects are written back to the database. Statistical forecasting utilizes information from the past (such as sales data) to predict what will happen in the future. When AutoES forecasting is chosen in RDF, a collection of candidate models is initially considered. The daily casual forecast process executes in the following manner: Preprocess the day-level promotional variables by multiplication with daily profiles. Does the time series contain enough relevant data to generate a forecast? The complexity penalty is necessary to avoid over fitting. A Simple Moving Average model assumes that historical data is too short or noisy to consider seasonal effects or local trend and is based on the level of the series. In the system, one of the key elements to producing accurate forecasts is using the system's ability to aggregate and spread sales data and forecasts across the product and location hierarchies. The BIC criterion rewards a model for goodness-of-fit and penalizes a model for its complexity. Does that mean that at 12 weeks the time series results are irrelevant and that at 14 weeks the sales plan has no value? Improve Forecast Accuracy with Oracle Retail Demand Forecasting. Confidence in the sales plan is controlled by the amount of sales data on hand and a Bayesian sensitivity constant (Bayesian Alpha), which you can set between zero and infinity. Figure 3-2 Forecast Level Selection Process. Bayesian Forecasting assumes that the shape that sales takes is known, but the scale is uncertain. Also, time series are often too noisy at that level. However, they were not designed to work with sales histories of shorter than two years. Calculate the causal forecast at the weekly level. It uses state-of-the-art modeling techniques to produce high-quality forecasts with minimal human intervention. The Oracle Retail Predictive Application Server (commonly referred to as RPAS) is a configurable software platform for developing forecasting and planning applications, following a Client/Server OLAP model. This method does not generate confidence and cumulative intervals when it is the final level method and no source level is specified.
